First Quarter 2022 Results

Sales for the three months ended March 31, 2022 were $182.3 million, an increase of 55% from the $117.8 million over the same period in 2021. Sales by reportable segment in the three months ended March 31, 2022 were as follows:

◾ Lindero recognized adjusted sales of $54.1 million from 28,619 ounces of gold ounces sold, a 45% increase from the same period in 2021. Higher gold sales were the result of increased performance at the three stage crushing and stacking facility.

◾ Yaramoko recognized adjusted sales of of $55.4 million from 29,530 ounces of gold sold.

◾ San Jose recognized adjusted sales of $45.9 million, a 17% decrease from the $55.3 million reported in the same period in 2021. Lower sales were driven by a 20% and 23% decrease in the volume of silver and gold ounces sold, respectively, which was driven by lower mined grades which was in line with Mineral Reserve estimates.

◾ Caylloma recognized adjusted sales of $26.8 million, a 7% increase from the $25.1 million reported in the same period in 2021.  The increased sales were mainly driven by higher zinc and lead prices.

Operating income for the three months ended March 30, 2022 was $40.7 million, a slight increase of $0.3 million compared to Q1 2021 as higher operating income at Lindero and the contribution from Yaramoko were offset by lower operating income at San Jose, higher Corporate expenses, and a $2.1 million write-down related to the termination of an exploration agreement on the Sante Fe property in Mexico.

Net income for the three months ended March 31, 2022 was $27.0 million, an increase of $0.6 million over the same period in 2021. Net income was impacted by a loss on financial derivatives of $4.2 million for the first quarter of 2022 compared to a $1.7 million gain in the same period of 2021. This was driven by a $5.2 million loss ($1.1 million realized, $4.1 million unrealized) on financial derivatives at the Caylloma Mine due to higher zinc prices that was partially offset by gains on fuel hedges at Lindero.

Outlook on Cost Inflation

The Company continues to monitor the impact of inflationary pressures on its cost structure and any deviation this could create from the guidance the Company issued at the beginning of the year. During the quarter ended March 31, 2022, the Company observed cost pressure on certain consumables including cyanide, diesel, explosives and grinding media while certain others remained relatively constant. Through the first quarter of 2022 the impact of inflation was below 5% of total cost. At the Lindero Mine, where diesel is the largest cost component, the effect of a rising price was partially mitigated by fuel hedges the Company has in place for approximately 55% of consumption in 2022. The future impact of inflation on costs remains uncertain at this time. The Company will continue to closely monitor the levels of cost inflation over the remainder of 2022.

Liquidity

Free cash flow from ongoing operations for the three months ended March 31, 2022 was $9.6 million compared to $11.8 million in Q1 2021. The decrease was driven by negative changes in working capital in Q1 2022 of $27.9 million and taxes paid of $20.1 million compared to a current income tax charge in the quarter of $11.9 million.

Total liquidity available to the Company as at March 31, 2022 was $150.4 million. The Company’s $200.0 million revolving credit facility was fully available as at the end of March 2022 and $40.0 million remained undrawn. Subsequent to March 31, 2022 the company drew down $20.0 million from the credit facility bringing the total amount drawn to $180.0 million of the available $200.0 million.

During the first quarter of 2022, the operation lost man-hours in January as a result of the sudden surge in COVID-19 cases causing a 14% shortfall in ore placed on the pad, compared to plan for the quarter. The Company is executing a recovery plan during the second and third quarters of the year and does not anticipate any impact on achieving annual production guidance.

In the first quarter of 2022, a total of 1,295,755 tonnes of ore were placed on the heap leach pad averaging 0.88 g/t gold containing an estimated 36,568 ounces of gold. Gold production for the quarter was 30,068 ounces, representing a 35% increase quarter-over-quarter.  Higher gold production is explained by an increase in the performance of the three-stage crushing and stacking circuits to design parameters, which delivered 100% of the 1.3 million tonnes of ore placed on the pad in the quarter compared to 19% or 0.4 million tonnes of the 2.1 million tonnes placed in the comparable quarter a year ago.  Mine production was 2.4 million tonnes of mineralized material with a strip ratio of 0.5:1.

Fortuna | 3

Cash cost per gold ounce sold was $692, compared to $615 in the first quarter of 2021. Cash costs per ounce of gold was higher due to higher consumable prices mainly related to diesel, cyanide and explosives and higher headcount as the mine had not reached its full complement of staff in the first quarter of 2022. This was partially offset by the higher volume of gold sold.

All-in sustaining cash costs per gold ounce sold was $1,038 during Q1 2022 compared with $1,055 in the first quarter of 2021. All-in sustaining costs for the first quarter of 2022 was impacted by the production issues described above and lower sustaining capital related to timing effects.

2 The Yaramoko Mine was acquired as part of the acquisition of Roxgold which completed on July 2, 2021. As such comparative figures for the comparative quarter in 2021 is not presented.

The Yaramoko Mine produced 28,235 ounces of gold in the first quarter of 2022 with an average gold head grade of 7.50 g/t; above the plan for the quarter. Gold production is on target to meet the upper end of the annual guidance range primarily due to mill feed grade being 9% higher than budgeted for the period. Positive grade reconciliation compared to the reserve model at the 55 Zone and additional tonnes from ore development explain the increase in grade.

Cash cost per gold ounce sold was $705, which was below plan, primarily due to higher production during Q1 2022.

All-in sustaining cash cost per gold ounce sold was $1,147 for Q1 2022, which was below plan due to higher production and lower sustaining capital related to timing effects.

The San Jose Mine produced 1,358,189 ounces of silver and 8,239 ounces of gold during the three months ended March 31, 2022, which represents an 18% and 20% decrease compared to Q1 2021. The driver for the decrease in production was primarily lower average head grades of 15% and 17% for silver and gold, respectively; which is in line with Mineral Reserve estimates.

The cash cost per tonne for the three months ended March 31, 2022 was $76.05 per tonne compared to $69.96 per tonne in Q1 2021. Cash cost per tonne in the quarter was in line with annual guidance.

The all-in sustaining cash cost of payable silver equivalent for the three months ended March 31, 2022 increased 14% to$15.32 per ounce, compared to $13.40 per ounce in Q1 2021. The increase in all-in sustaining costs was primarily the result of lower silver equivalent ounces sold and an increase in sustaining capital due to additional spend on mine equipment, partially compensated by lower royalties and mining taxes and lower worker’s participation.

The Caylloma Mine produced 311,939 ounces of silver, 9.1 million pounds of lead and 10.8 million pounds of zinc during the three months ended March 31, 2022. Silver production was 17% higher than the comparable period, driven by a 16% increase in average head grade from the contribution of newly scheduled higher-grade production stopes located in level 16 of the Animas vein. Lead production was 12% higher than the comparable period due to higher grades while zinc production was 10% lower than the comparable period due to lower grades. Gold production totalled 258 ounces with an average head grade of 0.16 g/t which was in line with expectations.

The production cash cost per tonne for the three months ended March 31, 2022 increased 8% to $89.60, compared to $83.09 in Q1 2021. The increase was the result of higher mining costs related to higher increased ground support and backfill requirements and increased plant costs related to steel and reagents. Cash cost per tonne in the quarter was in line with annual guidance.

The all-in sustaining cash cost for the three months ended March 31, 2022 decreased 4% to $17.83 per ounce compared to $18.50 per ounce in Q1 2021. The decrease was driven by higher silver equivalent production.
